HEATING-STOVE.

Application led January 9, 1915.

l-ie it known that l. RALPH Amaxaxonu Garnier, a citizen of the United States. residng at (nrarfield. in` the county of Whitman. andl State of Washington, have invented certain new and usefull Improvements in Heating-Stoves; of which the following is a specification, reference being had to the. accompanying drawings.

This invention relates to an improved heating stove, and has for its primary object toprovide an improved stove construction in. which wood` is used as fuel'. whereby all of the heat components may be withdrawn from the smoke as it arises through the stove drum and. passes into the flue or outlet.

The invention has for amore particular object to provide an improved stove of the above type embodying a plurality of air fines or passages around and about which theflame and smoke are adapted to circulate whereby the air in saidpassages draws practicallv allV the heat out of the smoke. and the creosote becomes crystallized and is deposited upon the walls of said passages.

l The invention has for still another object to provide a door in the back wall of the stove whereby the rcrystal deposits may be periodically removedand the walls of the passages cleaned, and the means carried by thel door for effecting an air tight closure of the same against the spaced air tlues.

' It .is an additional general object of my inventiontoimprove and simplify the construction of stoves of the above type, and to4 obtain a maximum?heating` capacity in the operation of such stoves,l from a minimum consumption of fuel.

"with the above and other objects in view, my invention consists in the novel features of construction, combination, and arrangement of parts to be hereinafter more fully described, claimed, and illustrated in the accompanyingl drawing. in which,

Figure l is a front elevation partly in section, of a heating stove embodying my invention 1n its preferred form; Fig. is a rear elevation thereof; Fig. 3 is a sideele paeity. This drum is supported by means of? the usual legs 6.

leading to the chimney, and 8 the usual feed door mounted in the front wall of the stove at its lower end.

Above the feed door 8 and the fire pot proper of the stove, a plurality of obliquely inclined passages or flues 9 are arranged. As clearly shown in Fig. l, these fines extend across the entire width of the stove and open at their opposite ends through the respective side walls thereof. Each of the air lines 9 1s constructed of sheet metal, and alternate flues are secured along one of their longitudinal edges to the front wall of the stove drum while the remaining flues are secured at their opposite longitudinal edges to the rear wall of said drum. In the illustrated construction, I have shown five such air flues, though it is to be understood "that a greater' or less number ofthe same may be provided in accordance with the capacity of the stove and the size of the apartments it is designed to heat. In the drawing, it will be noted that the upper and lower flues and the central flue are secured to the front wall of the stove drum. The other two fines, at their rear edges and at their ends, are secured to the back wall'of the drum for a purpose which will be later referred to. These tlues are properly spaced apart, and the other or free ends of the tlues are spaced from the contiguous walls of the stove, whereby a circuitous smoke passage indicated at l0 is produced. This passage, at its upper and lower ends. communicates at the back or rear of the stove with the spaces above and below the series of flues, respectively. The lowermost air flue is constructed of comparatively heavy metal, as it is disposed for direct Contact by the flame and is. therefore, subjected to the most intense heat. `The metal sheet of the next air iue is slightly thinner, and the walls of the remaining fines decrease in thickness to a corresponding degree.

The rear wall of the stove drum is 'provided with an opening indicated at l1, adapted to be closed by the hingedly mounted door l2. The door l2 is provided upon its inner face with the spaced ohliquely inclined heads or ribs 13. These ribs or beads are adapted to tit tightly into the open rear edges of the fines 9 which, as above stated, are fixed at their ends to the rear wall of the stove. Thus, said flues are securely closed and all possibility of the escape of air therefrom into the smoke passage, is preeluded, while, on the other hand, smoke cannot enter said fines between the fiue walls and the door 1Q.

In the voperation of my improved stove, the wood'cis placed in the fire pot and ignited. The air passes into the lowervopen ends of the flues 9 and upwardly through the same. It is apparent that, if desired, pipes may be suitably connected tothe upper ends of the several inclined passages and extended to difi'erenta partments of the building to convey the heated air thereto. The smoke arising from the fuel passes to the back of the stove and around the lower air fiue 9, thence 'upwardly aga inst the walls of the second air flue and forwardly to the front of the stove, then again backwardly and around the next flue, until the smoke nally enters the upper portion of the stove at the back thereof and is carried off through the smoke pipe 7. In this circuitous passage of the smoke, the air passing through the several hues-9 becomes highly heated, and practically all of vthe heat components is drawn from the smoke so that the volumev of thevlatter is reduced and the smoke may pass olf through a comparatively small outlet. As the heat is withdrawn from the smoke,` the' latter being reduced in volume, travels more andv more slowly so that all comparatively heavy particles therein Settle upon the walls of the air flues. The creosote in the wood is also crystallized. This creosote and other foreign matter may be periodically removed from'the walls of the air iues and said flues .thoroughly cleaned by opening the door l2 and scraping the iue walls. In actual practice, it has been demonstrated that two rooms, having 4560 cubic feet of space, may be comfortably heated during weather of about 20 Fahrenheit with a consumption of one cord of pine wood for sixty days. It is, thus, obvious that my improved stove may be very economically operated. The smoke outlet pipe does not become highly heated, because, as above stated, practically all the heatV is withdrawn from the smoke before it enterssaid pipe and,.in fact, it is possible, during the operation of the stove, to place the handupon the smoke outlet pipe without pain. In the test operation above referred to, it was found that, in about three weeks, the space between the air fiues became :choked .with deposits of creosote. These smoke passages and the walls of the air flues should, therefore,be cleaned weekly, in order to obtain the best results.

From the foregoing description, taken in connection with the accompanying drawing, the construction, manner of operation, and several advantages of my invention will be clearly and fully understood.I

In the use of wood burning stoves as heretofore constructed, the said stoves consume comparatively large quantities of wood, and it has been my primary purpose to produce a stove construction whereby substantially all of the heat units will be advantageously utilized, and the consumption of fuel correspondingly reduced.

It is obvious that the stove structure may be variously modified to conform to particular conditions or circumstances, and I do not, therefore, desire to be limited in putting my invention into practice to the particular combination and arrangement of the several elements, as illustrated in the accompanying drawing; but reserve the privilege of resorting to all such legitimate changes as may be fairly embodied Within the spirit and scope of the invention as claimed.

Having thus fully described my invention, what I desire to claim and secure by Letters Patent is:-

The herein described heating stove including a drum, a plurality of equidistantly spaced inclined air fines of uniform area opening at their ends through the opposite side walls of the drum, one of the longitudinal edges of the alternate flues being secured to the front wall of the drum and the other edges of said fines closed and spaced from the rear wall of thedrum, the remaining flues-being secured at their ends and at their rear edges to the rear wall of the drum and closed at their forward edges and spaced from the front wall of the drum, a clean-out door mounted in the rear wall of the drum, said latter 'fiues being open across the door opening, and a plurality of'obliquely inclined ribs on the inner face of said clean-out door tov fit within the openings of said flues and efl'ect an air-tight closure between the saine and the door. V

In testimony whereof I hereunto afiix my signature in the presence of two witnesses.
